CLUTCH FOR PAPER-ROLLS.

To all whom it may concern:

Be it known that I, WARD A. LOUNSBERRY, a citizen of the United States,residing at Kalamazoo, count-y of Kalamazoo, State of Michigan, haveinvented certain new and useful Improvements in Clutches for Paper-Rolls, of which the following is a specification.

This invention relates to improvements in clutches for paper rolls.

In the manufacture of paper, the finished productis wound upon suitablecores, com monly pieces of pipe, which are supported by a suitableshaft. The roll is driven from the shaft. It has been quite commonpractice, heretofore, to use collar-like clutches of wood and clamp theclutches against the roll by means of a small rope, the rope beingengaged over a screw or pin on the shaft and wound against the collar.These clutch collars must be applied while the shaft is revolving at ahigh rate of speed. Owing to the operators sometimes becoming entangledwith the rope, serious accidents have occurred, the number of accidentsand danger being such that in some instances laws have been enacted toprohibit the use of the dangerous devices.

The main objects of my invention are: First, to provide an improved rollclutch which can be quickly applied while the shaft is in motion withoutdanger to the operator. Second, to provide an improved roll clutchembodying these advantages which is very elfective. Third, to provide animproved roll clutch which is simple and economical in structure.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisapplication, in which:

Figure I is a detail longitudinal section through a structure embodyingthe features of my invention taken on a line corresponding to the brokenline 11 of Fig. III, my improved clutch being shown in operativerelation to a roll of paper, the shaft and a portion of the roll corebeing shown in full Specification of Letters Patent.

lines. Fig. II is a plan view of one of my improved clutches. Fig. IIIis atransverse section taken on a line corresponding to line 33 of Fig.IV. Fig. IV is a plan view corresponding to that of Fig. II, with thehousings for the catch removed. Fig. V is a detail perspective, showingone of the hinges for the clutch member sections, the

sections being swung apart.

In the drawlng, s1m1lar reference characters refer to s1m1lar parts.throughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the shaft 1 is M provided with suitablebearings and driving connections not illustrated. The core 2 is a pieceof pipe, such as is commonly used for On the shaft 1 is a core member 3having oppositely tapered ends, the core 2 being arranged on the innerend, and a (sileeve-like shaft member 4 on the outer en The shaft member4 is secured by means of the collar 5, which is adjustably held inposition by the set screw 6. The collar is provided with a recess 7 forthe set screw.

EThe collar is provided with an adjustable section 27 which is taperedto receive the vided with an inwardly-projecting flange The coactingclutch member 10 is provided with an outwardly projecting flange 12,which engages the end of the roll of as 13. The clutch members arecylinthe sections being hinged to each other so that can be swung apartto be placed on the shaft. The hinges are preferably in the form of thearms 1 1 on one section which at 15 to the flanges of the othersections. The edges of the flanges are cut away at 16 to allow thesections to swing apart.

The clutch members are threaded together, the member 9 being externallythreaded, while the member 11 is internally threaded, so'that it isadjustably mounted on the member 9. A catch is mounted on the member 11and consists of the fixed catch member 17 and the coacting catch shaftmember 4. By adjusting the member :27 the parts may be effectivelyclamped up. i The shaft member 4: has a series of peripheral grooves 8.The clutch member 9 is prodogs 18, the member 17 being provided with ahead with which the dogs 18 engage, the dogs being pivoted at 19 andyieldingly supported by means of the U-shaped spring 20. Housings 21 and22 are provided for the catch members.

The button 23 is provided with a head 24:, which coacts with theinclined surfaces 25 of the dogs 18, see Figs. III and IV. I thus securea simple compact spring catch which automatically engages when the partsare brought together.

The clutch member 9 is provided with a flange 26 at its outer end, thecatch being arranged between the flanges 12 and 25 so as to be guardedthereby.

In applying the clutch, the catch is released and the sections swingapart on their hinges. In order to do this, it is necessary to bring thejoints of both clutch members into alinement. The opened clutch membersare then placed over the shaft and closed with the flange 10 in one ofthe grooves 8 of theshaft member 4. The catch automatically engages, sothat the operator is merely required to swing the sections together. Theclutch member 11 is then held either by grasping the flange 12, or bymeans of a stick or tool. This, owing to the threaded engagement of theclutch member moves the member 11 over into engagement with the end ofthe roll. When it clamps the roll with driving engagement, it isreleased. This adjustment is quickly effected and without danger to theoperator. Further, the clutch is a very effective one.

I have illustrated and described my invention in a simple and practicalembodiment.

I am aware that various structural modifications are possible, but asthese structural modifications will no doubt be readily understood bythose skilled in the art to which this invention relates, I have notattempted to illustrate or describe the same herein.

- Having thus described my invention, what- I claim is new and desire tosecure by Letters Patent is:
